== Firefox 4.0b1

Every time starting Firefox beta (4.0b1) I get a javascript application popup error saying "what happened:TypeError: Components.classes['@mozilla.org/extensions/manager;1'] is undefined" before the browser opens. Clicking OK closes popup, browser opens to empty page (incorrect). Browser refresh reveals expected content.

== i have installed the FF4

Ok so as many other people have already put on here, whenever I try to send feeback to firefox by saying it made me happy or sad in the new firefox 4 beta, it says I need to download it. I have already tried the open about:config and done all that, reset any user ones and it still has no effect (yes I have closed and re-opened firefox).

And now using the button to see what it tells me, it tells me that it knows it is this version, different to everyone else with this problem.

== I used the beta

I just upgraded to firefox 4.0 beta but I see that firefox 3.6 is still on my machine. Several of my add-ons will not work with it. The Aardvark, Adblock Plus, eHow earnings tracker, Microsoft .NET, and WOT, all are incompatible with the 4.0 beta. But when I try to reopen the old format it only comes up as the foxfire 4.0 beta. How can I change back so my add-ons will work or should I just keep the 4.0 beta and can they be made to work with it? Thank You

I do not use bookmarks at all and I do not want them clogging up my UI.

Does anyone know how to remove the bookmarks button forcefully present in Firefox 4.0b1 when the Bookmarks bar is hidden?

Thanks! :)

Issue

I have another kind of problem with Firefox

Description

I want to know how to hide the new tab button especially when (to be specific) tabs[[overflow="true"] I have tried to modify this code:

.tabs-newtab-button { display: none } but during overflow the new tab button again shows up. This may not be the right place for such questions, still i needed a solution

Firefox 4 beta1 is not showing the new UI (no Firefox Button on the left). It's exactly the same as FF's 3.6.8, minus the tabs on top feature. Also if I disable the menu bar, the UI get's screwed up
